Pale silicone gaskets and plug-in seals beside an open precision mold.

Product Overview

The TDS describes a flexible 30 Shore A elastomer and a compression-set value measured after the stated post-cure condition.

Key Features

  • A two-component, addition-curing liquid silicone rubber for injection-molded gaskets and flexible sealing components.

Selected values from the original TDS. Refer to that document for conditions and whether values are typical or specification limits.

Typical Applications

  • Injection-molded silicone gaskets and plug-in sealing components.

Technical Considerations

Mix A and B at a 1:1 ratio and keep the mixture below 35°C before molding. A reference cure is 130°C for 5 minutes; actual time depends on part thickness. The compression-set value requires the stated post-cure. Typical values are not specifications; consult the SDS.
